Sprinkler System Required refers to the legal or safety obligation to install a sprinkler system in certain buildings or areas. Depending on the type of building, its occupancy, and local building codes, sprinklers may be required to meet fire safety standards. The installation of sprinklers is particularly important in high-rise buildings, hospitals, and industrial facilities where the risk of fire is higher. This requirement helps ensure that fires are suppressed as early as possible, providing valuable time for occupants to evacuate and minimizing property damage.
